You might consider a DBX 223xl. Available fairly cheap. Balanced input and outputs, master gain control, and individual gain control over hi/lo. I use two of them as three way xovers. Very flexible, all pots are stepped. You can change the frequency on the fly, without a noise penalty.
Bi amp pros out there I could use some help! First time Bi Amping...
Just picked up a BAT vk 200 for the bass and using my Pass Aleph 5 for the mids and tweets. Ive never played around with bi amping so I apologize in advance for any lame questions My speakers are Dunlavy SC3's original 5.5 nominal load. The pass is 90 wpc at 4 Ohm and the BAT is 200 wpc at 4 ohm so Im guessing around 75 wpc off the Pass Amp and 150 plus with the Bat Amp. My pre amp is a Aleph P and Im running the Single ended through a XLR adaptor (cause the Bat is Balanced inputs only) and the pass Aleph 5 off the XLR outputs of the pre and inputs of the Pass amp. The PASS Pre Amp manual says there is a 6db differential between the RCA and XLR outputs two and both can be driven at the same time. So the RCA is 9db and the XLR is 15 db. Gain is within 2db on each amp. So whats the best way to do this? Get a custom XLR "Y" connector and drive both off the XLR output of the pre? Or is there a way better way to get the magic? This is past my "WORLD" Map and experience so Id thought Id ask for the smart people for advice.
Thank you in advance!

haywood310 This should sound very good. Because you have amps that are not identical, vertical bi-amping is out. You’ll have to do horizontal bi-amping. http://www.av2day.com/wp-content/uploads/2014/05/biamp1.jpg And because there’s no way both amps will be equal in gain, you’ll have to put a passive volume control at the input of the loudest amp so you can lower it’s volume to be identical to the other amp. https://www.schiit.com/products/sys Then your main preamp volume control will be the master volume control for both amps that now have identical gains.

Hi George, See item 1 in my post earlier in the thread. As well as the statement earlier in my post that I'm assuming the specs are accurate. Best regards, -- Al |
Saw it Al, but it's more war and peace than mine, think it could loose him. And he should just use these for the Bat to give single ended https://au.rs-online.com/web/p/products/0448351/?grossPrice=Y&cm_mmc=AU-PLA-DS3A-_-google-_-PLA_AU_EN_Connectors-_-Rf_And_Coaxial_Connectors-_-PRODUCT_GROUP&matchtype=&pla-441403653319&gclid=EAIaIQobChMIiOau7Yup4gIVToyPCh12qgSdEAQYAiABEgKPxfD_BwE&gclsrc=aw.ds Cheers George |
